International Charter on Space and Major Disasters
An International agreement among Space Agencies to support with space-based data and information relief efforts in the event of emergencies caused by major disasters. - Disaster response - Multi-satellite data acquisition planning - Archive retrievals and spacecraft tasking - Data processing at pre-determined level - Space Agency contribution in image/data - Space Agency initiative for
value-added-data fusion Initiated by ESA and CNES in 1999 15 full members (as of August 2012)

German Satellite Data Security Act of 2007 “Satellitendatensicherheitsgesetz” (SatDSiG)
The permit … must be granted if the dissemination of data in the individual case does not harm the vital security interests of the Federal Republic of Germany, does not disturb the peaceful coexistence of nations and does not substantially impair the foreign relations of the Federal Republic of Germany.
To ensure reliable basis for commercial operations and data distribution

SatDSiG Check
• Special users and sensors? • Area Sensed? • Resolution and Phase. < 2,5
m/ 1,2 m (SpotLight Mode)? • User? • „Sensitive“ does not deny
the acceess, but requires individual check by BAFA
Applicable in Germany for: - TerraSAR-X - TanDEM-X
.. Not for: RapidEye, EnMAP… Non German VHR optical data received and distributed from Germany

Inuvik Satellite Station Facility (ISSF)
- DLR antenna complements northern European stations for TanDEM-X reception
- Major investment of Germany/DLR in partnership with European and Canadian entities
- Canada Center for Remote Sensing (CCRS) owns site, supports & develop Inuvik Satellite Station Facility (ISSF)

Inuvik Satellite Station Facility (ISSF) – Legal issues
Canadian Remote Sensing Space Systems Act
Controls any EO activity of Canadian satellites and for any EO satellites from Canadian territory
The case: German EO station receives German EO satellite in Canada
German SatDSiG: no foreign access to TerraSAR-X data
Canadian RSSSA: permit requires Canadian access to foreign EO data
bilateral intergovernmental agreement

Sentinel Satellites Data Policy - Free and Open access to all Sentinel-data (everybody, at no cost) 1,2
- Free and Open access to all GMES Core Service Products 2
- Contributing missions keep their data policy (incl. commercial). Licence for data are purchased by GMES for Core Services. Some licences may be extended for general public use
Status - ESA member states recommend this data policy to the European Commission - Through GMES regulation 911/2010 need to put this into a legal act - General „Governance of GMES“ still tbc!
GMES Data Policy
1: User registration required;
standard off-line products; standard internet access
2: Security restrictions may apply. E.g. Security Services

Conclusions
- Earth Observation Data required to cope with societal challenges Beyond commercial drivers.
- Harmonize national policies in granting/denying access to data Towards an international solution?
- Get sustainable and stable conditions for long term observations Don‘t forget the historical data!
